The aim of this study was to determine the efficacy of tart cherry (TC) supplementation on recovery following strenuous exercise. A systematic review and meta-analysis were conducted using studies investigating TC supplementation on measures of muscle soreness, muscular strength, muscular power, creatine kinase, C-reactive protein, Interleukin-6, and tumor necrosis factor alpha. A literature search ending in July 2020 was conducted in three databases (SPORTDiscus, Web of Science, and PubMed). Data from 14 studies were extracted and pooled for analysis. Tart cherry supplementation had a small beneficial effect in reducing muscle soreness (effect size [ES] = -0.44, 95% confidence interval [CI] [-0.87, -0.02]). A moderate beneficial effect was observed for recovery of muscular strength (ES = -0.78, 95% CI [-1.11, -0.46]). A moderate effect was observed for muscular power (ES = -0.53, 95% CI [-0.77, -0.29]); a further subgroup analysis on this variable indicated a large effect of TC supplementation on recovery of jump height (ES = -0.82, 95% CI [-1.18, -0.45]) and a small significant effect of supplementation on sprint time (ES = -0.32, 95% CI [-0.60, -0.04]). A small effect was observed for both C-reactive protein (ES = -0.46, 95% CI [-0.93, -0.00]) and Interleukin-6 (ES = -0.35, 95% CI [-0.68, -0.02]. No significant effects were observed for creatine kinase and tumor necrosis factor alpha. These results indicate that the consumption of a TC supplement can aid aspects of recovery from strenuous exercise.
本研究的目的是确定补充酸樱桃（TC）对剧烈运动后恢复的功效。我们进行了一项系统评价和荟萃分析，纳入了研究补充TC对肌肉酸痛、肌肉力量、肌肉功率、肌酸激酶、C反应蛋白、白细胞介素-6和肿瘤坏死因子α等指标影响的研究。于2020年7月在三个数据库（SPORTDiscus、科学网和PubMed）中进行了文献检索。提取并汇总了14项研究的数据进行分析。补充酸樱桃在减轻肌肉酸痛方面有较小的有益作用（效应大小[ES]=-0.44，95%置信区间[CI][-0.87，-0.02]）。在肌肉力量恢复方面观察到中度有益作用（ES=-0.78，95%CI[-1.11，-0.46]）。在肌肉功率方面观察到中度作用（ES=-0.53，95%CI[-0.77，-0.29]）；对该变量的进一步亚组分析表明，补充TC对跳高恢复有较大作用（ES=-0.82，95%CI[-1.18，-0.45]），对短跑时间有较小但显著的作用（ES=-0.32，95%CI[-0.60，-0.04]）。在C反应蛋白（ES=-0.46，95%CI[-0.93，-0.00]）和白细胞介素-6（ES=-0.35，95%CI[-0.68，-0.02]）方面均观察到较小作用。在肌酸激酶和肿瘤坏死因子α方面未观察到显著作用。这些结果表明，食用酸樱桃补充剂有助于剧烈运动后的恢复。
